Depending on the type of marble, its color and veining, you might want to either opt for large floor tiles or for smaller ones that together form a mosaic with a unique pattern. Large tiles are best for showcasing soft and uniform marble veins and patterns.

Where other traditional house-heating methods can leave patches of draftiness or downright chilliness (think hallways, or corners of large rooms), underfloor heating is evenly dispersed and consistent. Kind of like an electric blanket, just under the floor.
